If it does not have the "penaly with shield" flag, it does the damage displayed in its stats. If it has that property then it does 25-35% (opinions on the exact number are divided) less damage and speed. In native, poles of less than 150 do not have the penalty, but the moder can choose to flag whatever they want.
this is wrong.
They removed the "penalty with shield"flag from all weapons
because it doesn't do anything. Nothing.All pole arms when used one handed [with a shield or on a horse] suffer a damage and speed penalty.
it is not a straight 30% dmg/speed decrease though, it is a bit lower and slightly different for all of them because of weapon speed variations,etc.
And yeah, Awlpike is the best hoplite weapon, then red tassle spear which is total baller
/bamboo spear is the super support hoplite with more reach, and beast anti cav -- although awlpike can do it just fine with proper footwork.
